Convex quads
Four-sided figures are called quadrilaterals. They could also be called quadrangles.
Here are some categories;
• Quadrilaterals that are equiangular
• Quadrilaterals that are NOT equiangular
• Quadrangles that are equilateral
• Quadrangles that are NOT equilateral
Give an example of a four-sided figure that fits in each category.
Are there four-sided figures that fit in NO category? Example, or why not?
Are there four-sided figures that fit in MORE THAN ONE category? Example, or why not?
